Yak'Talon

From Memory Alpha, the free Star Trek reference.

Yak'Talon was a Jem'Hadar soldier during the Dominion War. In 2374, he served as the Seventh under the Vorta Keevan. After their ship crashed on a planet in a dark-matter nebula, he was assigned to repair their communications system so they could send a distress call. This task would have taken ten days, and the Jem'Hadar had insufficient ketracel-white to last until then. Yak'Talon and the rest of his unit were killed in a deliberate ambush ordered by Keevan so that he himself could survive in Starfleet custody. (DS9: "Rocks and Shoals")
